To this end, in the UK, the DWI have issued their guidelines for UV operation and system selection to the UK water industry. A key feature of their guidance is UV system validation. Validation refers to a series of 3rd party testing to ensure the performance of an Ultraviolet system design under a range of operating environments.
The DWI guidance states:
"DWI recommends any water company considering the use of UV irradiation for the disinfection of public water supplies to consult the US EPA Ultraviolet Disinfection Guidance Manual (US EPA UVDGM)"
As an industry leader with considerable experience in supplying US EPA Validated UV systems for drinking water applications, atg UV Technology are well placed to support and advise all drinking water companies on the application of the DWI guidelines, including validation, log reduction, RED Dose, installation into existing infrastructures, upgrades and retrofits, ongoing industry regulation and future product development.
atg UV have designed and developed a large range of UV systems specifically for municipal drinking water and wastewater applications, which are fully compliant with the requirements of the DWI 2010 guidelines.
atg UV's product range offers fully validated and 3rd party tested US EPA UVDGM systems that deliver a 1 - 5 log reduction of Cryptosporidium for flows as small as 10 m3/hr to over 2000 M3/hr within a single high output, small footprint, medium or low pressure system. For larger flows, systems are offered as packages, utilising units placed in either series or parallel configurations.
Additionally, atg UV have been asked to present to a number of drinking water companies throughout the UK. This is a free service offered by atg UV and is open to any municipal water company or contractor interested in learning more about UV disinfection technology.
